74AHCT244

74AHC244; 74AHCT244 Octal buffer/line driver; 3-state Rev. 05 — 20 December 2007 Product data sheet 1. General description The 74AHC244; 74AHCT244 is a high-speed Si-gate CMOS device. The 74AHC244; 74AHCT244 has octal non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. 2. Features s Balanced propagation delays s All inputs have a Schmitt-trigger action s Inputs accepts voltages higher than VCC s For 74AHC244 only: operates with CMOS input levels s For 74AHCT244 only: operates with TTL input levels s ESD protection: x HBM JESD22-A114E exceeds 2000 V x MM JESD22-A115-A exceeds 200 V x CDM JESD22-C101C exceeds 1000 V s Multiple package options s Specified from −40 °C to +85 °C and from −40 °C to +125 °C 3.
